Description

【Technical field】

[0001] The invention relates to a lighting appliance, in particular to an AC LED lighting lamp. 【Background technique】

[0002] Since Edison invented the electric light in 1879, this great creation has brought mankind into a new century full of light and infinite possibilities. The emergence of artificial light sources has been recognized by the international scientific and technological circles as a milestone in the beginning of modern civilized society. From the earliest carbon filament lamps with a lifespan of only 8 hours, to incandescent tungsten filament lamps, fluorescent lamps excited by high-voltage fluorescence, high-pressure sodium lamps that emit light using atomic spectral line transitions, mercury lamps, spiral energy-saving lamps, etc., lighting fixtures based on various light-emitting principles can be described as The variety is complete and the patterns are various. However, the long life, high light intensity and low energy consumption o...
